Need A “Genuine” Native/US Writer [Help Me to Find Please]

Hello, good people.
Could you suggest a genuine US writer, please?
I have hired someone from this group, who claimed that he has a few native US writer in affordable price, and what he offered is little better than "Rubbish", and numerous grammatical mistakes all around.
Could you please suggest one/ share your experience with REAL NATIVE WRITERS here or somewhere else, please?
Need tons of articles.
Thanks in advance.
